Leroy Somer Automatic Voltage Regulator R713

Available for sale 2 x NEVER USED Leroy Somer Automatic Voltage Regulator R713. The 3F R713 or R723 modules are used in connection with a R200 series regulator for equalizing the voltage of an alternator with that of the network before coupling, when the installation operates automatically or when manual equalization of these voltages is not possible. This prevents excessive current caused by coupling a network to the machine when both are not at the same voltage. This difference in voltage is usually due to fluctuations in the network voltage because the alternator is regulated at a constant voltage except for cases of voltage droop). On some networks these fluctuations can reach ± 10%. Equipment never used and in good working conditions.
